# Which files appear in release tarballs?
#
# The .resources.dll files appear in release tarballs, because the GNU Coding
# Standards say in
# <https://www.gnu.org/prep/standards/html_node/Utilities-in-Makefiles.html>:
#   "The configure script and the Makefile rules for building and installation
#    should not use any utilities directly except these:
#      awk ... true"
# and 'msgfmt' is not in this list.  In other words, when a user - who does not
# have the GNU gettext tools installed - does "make && make install", it should
# install the .resources.dll files.  The only way to achieve this is to include
# them in the release tarballs.
#
# The .pot file appears in release tarballs, because it is needed when a
# translator runs "msginit" to start working on a PO file or when a web-based
# PO editor prepares the initial PO file for a translator.  Translators and
# translation projects should not have to run 'xgettext' on some source code;
# that's not their business, and they would not be in a good position to deal
# with errors.
#
# The .po files appear in release tarballs, because
#   - They are part of the source code of the .resources.dll files, and it would
#     be a bad idea to include the (generated) .resources.dll files without
#     their corresponding source code. Even if the .po files can be found on
#     some translation project's site or in some separate git repository, users
#     and distributors should not have to go that far, to hunt them down.
#   - The .po file is needed when a translator runs "msginit" to continue
#     working on a PO file (in packages that do not use a web-based translation
#     project).
# These .po files are those that the translators submitted or committed in
# version control, or a translation project's daemon committed on behalf of the
# translators.
# Up until 2025, we included the *merged* .po files in the release tarballs.
# These merged .po files, that we now name .gpo files in this Makefile,
# are neither source code nor entirely generated files: They are a mix of
# source code (from the translators) and generated parts (from the .pot file).
# This caused two problems:
#   * Regarding the tarballs: They are "non-source" files in the sense of
#     <https://www.gnu.org/prep/standards/html_node/Releases.html>.
#     Distributors who want to make sure that they rebuild everything from
#     source had a problem here.
#     Also, small changes in the package caused massive line number changes
#     in the .po files.
#   * Regarding version control:
#     Packages that put the .po files under version control had changes in
#     all .po files nearly each time "make dist" was invoked. Leading to
#       - Lots of modified files shown by "git status",
#       - Frequent merge conflicts when merging between branches,
#       - A voluminous version control history.
#     Whereas packages that do not put the .po files under version control
#     had to fetch them from somewhere (usually a translation project),
#     meaning that an 'autopull.sh' step was needed before the 'autogen.sh'
#     step of the package's build system.
# Instead, now, we include the original .po files in the release tarballs.
#
# The .pot file, stamp-po, .po files, and .resources.dll files appear in release
# tarballs. The GNU Coding Standards say in
# <https://www.gnu.org/prep/standards/html_node/Makefile-Basics.html>:
#   "GNU distributions usually contain some files which are not source files
#    ... . Since these files normally appear in the source directory, they
#    should always appear in the source directory, not in the build directory.
#    So Makefile rules to update them should put the updated files in the
#    source directory."
# Therefore we put these files in the source directory, not the build directory.

# This target fetches the PO files, produced by translators, from a
# translations project's site on the internet, and generates the associated
# LINGUAS file (for packages that use such a translations project and where
# this translation project does not already commit the PO files and the LINGUAS
# file into the version control repository of the package automatically).
